To all whom it may concern:

Be it known that I, Fos'rnn MILLIKEN, a citizen of the United States, and a resident of Lawrence, in the countyvof Nassau and State of New Yorlghave invented a new and lmproved Alloy, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved alloy more especially designed for use in mine water valves and other devices subjected to Weak acids.

The alloy consists of the following metals in approximately the proportions specifie namely: V

' Copper 4:2 to 52 per .cent.

Nickel Lead 22 to 30 Specification of Letters Eatent.

Application filed October 8,

mine water containing Patented 3i, ELE QQ;

1919. Serial no. 329,275.

' These metals are melted together and cast in the usual way, and the resultant alloy is especially serviceable to resist the corrosive action of weak acids, such, for instance, as

a to 600 grains of sulfuric acid per gallon, or tartaric acid under 10%, or phosphoric acid under 10%,

I claim: 1. An alloy formed per cent, nickel 22 to 22 to 30 per cent.

2. An alloy containing copper, nickel, and lead, of which the percentage 0 the from copper 42 to 28 per cent, and lead nickel and the lead is approximately equafl and approximately one-half of that of the copper. v
